. IMPROVBD MACHINE FOR FILLING HORSE-GOLLAI-ti.

TKO ALL WHOM IAT MAY CONCERN:

Be it known that we, A. Scnnrox and H. HILDENBRAND, of the city and county of St. Louis, State of Mis souri, have invented certain n ew and useful Improvements in-Machines for Filling Horse-Collars, and for similar purposes; and we do 'hereby declare the following to be a full and true account thereof, reference being had to the accompanying drawings, and to the lettersoi' reference" thereon. l

Th-e object of our said invention is to till or stuit horse-collars or similar bolstered appliances rapidly and thoroughly, and the general nature of our said invention is in certain improved devices, and methods of apply ing the same, as will more fully now appear. Of said drawings p Figure 1 is a general front elevation,

Figure 2 is a general plan, and- Figure 3,3. partial longitudinal section. v By reference to our former patent, numbered 59,726, and issued to us on the 13th of Noven1ber, A. D.

41866, it will be observed that the improvements herepreseuted refer especially to the feed of straw .or other` stuiing-materal into the feed-funnel, and we will, therefore, in the following, specially describe only such parts of the machine, as shown by aforesaid'drawings, as will diiier from-such parts shown and fully described in our patent aforesaid. d

We support the machine parts upon a proper frame, A, at one' end whereof power may be taken from a ilyv wheel, B. The l arm b, to'whichr the connecting-rod 6l attaches, is slotted in such wise that the stroke may be varied. The cross-head is moved by b1, being well guided inthe guide-bars 63. From the cross-head the reciprocating motion is transmitted directly to the plunger or 511er C. This, in its reciprocating motion, plays in the tube C. The straight unfilled colla-r is held byv proper Ytongs D to a support, D,'these being secured to a sliding bed, E. The support D1 serves also as a guide for the feed-tube C.- l(ln the other end of the sliding bed E-are the gripers D, to hold the rear end of the collar whilst .being stufed. Thel bed E move'son the lower bed-plate E to regulate the sliding motion. The set-screws e maybe tightened up, so as, by pressing against E, (they being held in E,) the said motion is retarded. A hand-wheel, el, operating, by the shaft e, the cog-wheel ea by gearing into the rack e4, on llil, may also be used to move When the collar is stretched vbetween D, D1, and D, and 'the plunger C is filling the same,this process will force the collar, and the bed E,

to which it is indirectly secured,'back, in accordance with the progress of the llingprocess. The hand-wheel e1 is afterwards used to bringE into proper position for subsequent lling, and so forth, whilst the set-screws e are used, to regulate the backward` motion of .E, as stated. All of this will also appear by reference' to our said Patent, No. 59,726. The feed-tube'C starts from a stationary hopper, F, into which the straw is thrown, and as the plunger C plays through the lower part of F., at' each stroke it takes, (by the serrated edges and end of 0,) the proper quantity of material from F, and carries the same through C into the collar on E. But in order that the plunger or stuier VC' should lin each stroke grasp the proper quantity of "material, the straw or other proper material must be guided or forced toward the rangeof C.

This feed' to C we accomplish in the following improved manner: The straw is thrown into the hopper F, near its upper end. To pass it'down toward the lower and narrower part of F, we use, rstly, the scrapersffl hav'nga vibratory motion. Of these, the scraper f-maybe secured by a pivot on the wall of F, and receive motion by a connecting-bar, f2, whichiagain receives motion fromthe crank f3 on the rocklshaft f". The Scrapers fl may be directly secured to f, thenfandf1 will vibrate irl-opposite directions, and an eiiicient feed ofmaterial be reached by the combined action thereof. The rock-shaftf* receives motion by the cranky, rodf, and rod f7, this being secured to a prong, g, ofthe .eccentric-bar G, which is driven by the main axle of the iiy. wheel B. The bar G may have any proper attachment to said main axle to give it a small reciprocating .motion corresponding to the plunger C. In this case we have made the attachment by the usual eccentric,lat g. After the straw has been 'guided down by the scrapersfandjl, the rotating shaft H, with its prongsh, throws it before theplunger Cto be duly pressed into C', asl above described. The said shaft H passes across the hopper F transversely. Outside ef F it has the toothed wheel h by which it is turned intermittently, the wheel being actedv upon by the prong g of the eccentric-bar G.

In case the material used is ne-cut straw, shavings, and such like, the scraperhooks ff1 may not he needed. 'One of the connecting-pins betweenj'6 :mdf1 may then be removedfand the scrapers thus thrown out of ploy on the lower side of H. However, a second rockinglshaft, I, may then be used to guide the material toward the plunger C. The shaft I, lying similarly to H, has similar prongs, z', and passes outside of F, .having a crank, i', which, by a. proper pin, may be connected.` with a lower prong, g1, of the eccentric-bar G. In this onse a, partition-piece, K, will usually be inserted in the hopperl F, as indicated1 in red lines, to properly guide the fine material to the forward end of the hopper F.

. We do in nowise limit our said invention to the special forms and connections of the devices here recited, but 'insist that any arrangenient equivalent in form or action is included in the nature of this our` claim.

Having thusr fully described our said invention, what we claim, and desire to fully secure by Letters Patent, is

1. The scraper or Scrapers ffl, and their combination with the rocl-shaftf, substantially as. andfor the purposes set forth.

2. The combination of the rotating 'shaft H and its prongs h with the roclbshixft I and its prongs z', substantially as set forth. t

3.- The eccentric-bar G, the shaft f, andthe shaft H, when combined and acting substantially as and for the purposes set forth.

4. The combination of the eccentric-bar G with the shaft, substantially as and for the purposes set forth. 5. The arrangement of the partition-piece K in the hopper F, substantially as and for the purposes set forth.
